1. Andrew Ellicott (Wikipedia).

Excerpt: Andrew Ellicott (January 24, 1754 – August 28, 1820) was an American land surveyor who helped map many of the territories west of the Appalachians, surveyed the boundaries of the District of Columbia, continued and completed Pierre (Peter) Charles L'Enfant's work on the plan for Washington, D.C., and served as a teacher in survey methods for Meriwether Lewis.
In 1796, George Washington commissioned Ellicott as the U.S. representative on the commission for the survey of the southern border between the Spanish territories along the Gulf of Mexico coast in Florida and the United States as negotiated in the Treaty of San Lorenzo (also known as Treaty of Madrid) of 1795. Ellicott travelled with a military escort from Pittsburgh via the Ohio and Mississippi rivers and worked together with Spanish commissioners, despite many difficulties, for the next four years.

Excerpt: The House on Ellicott Hill stands on property acquired as a Spanish grant in 1797 by Natchez merchant James Moore. The hill was the site of the encampment of Andrew Ellicott, sent by President George Washington to survey the boundary of the new Mississippi Territory with Spain. According to Dr. William Morton ("Andrew Ellicott, Stargazer"), it was Ellicott who first raised the American flag from this hill, to which Spanish Governor Gayoso responded by aiming his fort's cannon in its direction.

3. Treaty of San Lorenzo (Wikipedia).

Excerpt: Pinckney's Treaty, also known as the Treaty of San Lorenzo or the Treaty of Madrid, was signed on October 27, 1795, by the United States and Spain. It defined the border between the United States and Spanish Florida and guaranteed the United States navigation rights on the Mississippi River. With this agreement, the first phase of the ongoing border dispute between the two nations in this region, commonly called the West Florida Controversy, came to a close.
